Left pelvic half shows type IIa Adachi’s classification—internal pudendal artery arises separately from internal iliac artery while inferior gluteal artery and superior gluteal artery arise by a common trunk which divides proximal to the pelvic floor. IIA: internal iliac artery; EIA: external iliac artery; IG: inferior gluteal artery; SG: superior gluteal artery; IP: internal pudendal artery.
